Conjugate Zeros Theorem

Additional Resources:

In this lesson, we will learn about the conjugate zeros theorem, which is also known as the conjugate pairs theorem. The conjugate zeros theorem tells us that if our polynomial function has real number coefficients, then our complex zeros will always come in pairs. So if a + bi is a zero, then a - bi is also a zero. We see examples where we will use this theorem to write polynomials given complex zeros and to find zeros of polynomial functions.
